 \section{Grid-based smoke}

 

 The visualization is done using a two dimensional grid as opposed to particle-based smoke visualization techniques. At every vertex a number of fluid attributes are

-stored. The skeleton program keeps track of the density, velocity and force. These attributes can be visualized with different techniques. Each and every attribute has its own 'preferred' visualization technique. \\

 \section{Internal structure}

 

-The first assignment was to simply compile the code. This was fairly easy. However, the code was a bit unstructured. Everything was put into one big file. To be able to add additional functionality without losing sight of what we were doing, we created a file for every new technique we implemented. Furthermore the calculations, rendering functions and user interaction code was split from eachother. \\

 \subsection{Height strips}

 

 When first implementing the height plots a third dimension was simply added when rendering the triangle strips for the smoke visualization. This had as an effect

-that the different rows of each of the triangle strips in the simulation where not connected. In stead of a height plots we implemented height strips. \\

 This problem was countered first calculating the height for each vertex and storing it in an array. When rendering a vertex, the correct value is then retrieved

 from the array to correctly display the height. \\

 \section{Description}

 

-Imagine dropping of bit of ink into the fluid and let it flow for a while. This will result in a line that shows the path a ink particle has taken. Such a path is called a streamline. A streamtube is a 3D variant of a streamline. It consists of a number of consecutive tubes that together form a thick 3-dimensional tube. \\

-Each streamtube has a begining and an end. The starting point of a streamtube is called a seedpoint. From this seedpoint the tube will begin flowing with the fluid. It ends after a number of frames. \\
